"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"He was fantastic. I had arranged for him to come to my house and for my husband to meet him that morning. I know my husband is somewhat difficult and he was very impressed with this gentleman. In fact, he was talking to me about redoing all of our pipes with him. So, I would say he’s the best one. A pipe had broken while we were on vacation, we called him when we got back from vacation. His zip code was 29643, and I was surprised that he would come all that way and he did. The guy was great. Price was excellent, but I have nothing to compare it to though. I thought the price was excellent, I’ve had things done in businesses in plumbing, so I’m familiar with that and I thought it was very reasonable, very fair, beyond fair. Especially with the drive there too. I just hope a lot of people don’t call him in case I need him again. He was excellent, very good."

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"We had another plumbing company come out due to a leak. Rather than do any diagnostics, they just replaced the pressure valve. It still leaked. I called the next Monday and was told oh, you need a new water heater. Johnny Gavilan from Preferred Home Services checked a couple things and found our expansion tank was bad. He did warn us there still could be a problem with the water heater but at least he checked first. If we need the water heater replaced, our expansion tank will be new!"

Water Heaters FAQs, answered by experts

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.
